We took some time to compare a couple of the top fat burners in Australia.

OxyShred (EHPlabs) and Burn Complex (Optimum Nutrition) are extremely comparable products, but with a few differences. They are both known as being excellent thermogenic fat burners. We decided to take the guess work out of which choice to make when it comes to deciding your fat burner, here is what we decided!

What does thermogenic mean?

As you would have thought, thermogenic means to produce heat. In the case of the fat burner, it means producing heat by stimulating your metabolism. 

OxyShred and Burn Complex are both incredible thermogenic but a deeper look into each of these products would certainly help you pick the more appropriate combination for your exercise goals. 

What makes Burn Complex (Optimum Nutrition) effective?

Optimum Nutrition Burn Complex Stim (has caffeine) Thermogenic drink mix is a 30-serve formula that is packed with clinically-backed fat burning ingredients that can be trusted. It contains Acetyl L-Carnitine, Caffeine, Green Tea Leaf Extract, Capsimax, and Guarana Extract. It doesn’t contain fat, sugars, and fewer carbs making it an extraordinary thermogenic drink that will burn fats, level up metabolism, and provide high and intense energy.


Now diving into OxyShred, what makes OxyShred (EHPlabs) effective?

An impressive 11-ingredient blend that literally makes one of the most effective and top selling fat burners in the world.

OxyShred uses a 4-way matrix that boosts energy, suppresses appetite, stimulates the metabolism and increases athletic performance. What we found to be super impressive about OxyShred was the energy it provides whilst still burning fat super efficiently.

The ingredient panel is extensive but the key takeaways are well above clinical dosages on Acetyl L-Carnitine, Conjugated Linoleic Acid (CLA), ketones to keep you thinking and a mood enhancing clinical dose of taurine. 

The key differences are:

OxyShred provides an extensive blend of ingredients that try to cover all basics - energy, mood and fat burning.

Burn Complex is more impressive if only looking for a natural all-round fat burner, but you will slightly compromise other factors when picking Burn Complex over OxyShred. Other differences are certainly the flavours.

Burn Complex has an impressive 3 flavours:

  • Strawberry Kiwi
  • Grape
  • Orange Lemon Lime

OxyShred has an impressive 6 flavours:

  • Mango
  • Passionfruit
  • Wild Melon
  • Pink Grapefruit
  • Guava Paradise (Our favourite!)
  • Kiwi Strawberry
